PTCKER-CHECK FOR LOOMS.

Specification of Letters Patent,

.Application filed July 10, 1911; Serial No. 637,596.

To all whom it may concern Be it known that I, EDWARD S. STIMPSON,

of Hopeda le, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Picker-Checks for Looms, of which the. following is a specification.

The present invention consists in certain improvementsjupon the character of picker inflthe accompanying drawings,- in whichv F-i'gure 1, is a plan View of the lay of a weft-replenishing loom, the central portion of the lay being broken away. Fig. 2, is-a front View of the parts of the lay shown in F ig. 1. Fig. 3, is an enlarged horizontal section in the plane indicated by the line 3-3'in Fig. 2. Fig. 4, is a vertical cross section in the plane indicated by the line Min Fig.1.

A, is the lay, having'a slot a, at its replenishing end for the downward discharge of the spent weft-carrierfrom the shuttle when the shuttle is at that end of the lay.

B, B, are thepickers and C, C, are the picker sticks. These parts are such as are ordinarily employed in the well-known Northrop loom, which is illustrated, for example, in United States Letters Patent of James H. Northrop, No. 529,940, November 27, 1894.

D, and E, are the picker checks at the opposite ends ofv the lay. Each picker check is a strap, preferably of leather, and is fasend of the lay above the same and outside of tened at the rear of the lay, passes across the and in line with the neighboring picker B,

and the 'two picker checks are operatively connected with each other at their ends which are located in front of the lay.

It is customary, as shown, for instance, in the 'Mooney patent, to have a single strap extending entirely across the loom and supplying checks for both pickers. This has been found to be inconvenient in automatic weft-replenishing looms, particularly in those of the feeler type wherein the rcplenishment is automatically effected while the run- 7 ning weft still remains intact, the replenishmg mechanism being called 1nto action by means of a feeler which passes through a slot in theshut-tle-box at the end of the lay remote from the replenishing mechanism and through a slot in the wall of the shuttle and into contact with the weft within the shuttle, the replenishing mechanism acting when the weft within the shuttle is reduced to a definite minimum. Such a fccler loom is shown, for example, in United States Letters Patent of William Haynes, No. 685,236, October 22, 1901. In the present drawings the front-plate F, is shown-provided with a slot 7), and the shuttle G, is shown with a slot 0, for the reception of the feeler. Ticker check straps such as have heretofore been in .use get in the way of the feeler and also in theway of the weft-carriers ejected downward through the slot at, in the l'ayat its replenishing side.

The principal object of the present invention is so to connect the two pickerchecks D,

and E, so that the feeler slot b, and the weft carrier discharge slot a, shall be wholly unobstructed by said connection. -The picker check D, is connected at its front end to the upper end of a lever H, which is centrally pivoted at (Z, to a bracket e, fastened to the front side of the lay below the shuttle-box. This lever H, is entirely outside of the feelcr slot D, and extends be-- low the bottom of the lay. Likewise the picker check E, at the replenishing end of the lay is connected at itsfront end with a lever centrally pivoted at b, to a bracket 9, fastened to the front side of the lay. This lever I is wholly away from thewveftcarrier discharge slot on and it extends below the bottom of the lay. The lower ends of the two lovers H, and I, are connected by a thrust rod J, which extends lengthwise of the layjust below the bottom threof.

This rod twhich is 'a stout metal wire) has an outwardly projecting bend l1, opposite the inner end of the slot (1, and the portion 2', of the rod which extends infront of the slot a, isadvancedsufficiently far so as not. to interfere with the free drop of the weftcarriers falling through 'said slot. It will Patented Oct. 7, 1913.

be noted that the bracket exitendsto a greater distance forward of t e lay than does 'wardly extending location 0 .nected so' the bracket e 'thus allowing for the forthe rod J. By reason of this construction the two picker checks are operatively conthat they do not interfere with functions, ofthe lay of an autoany of the .matic feeler weft-replenishing loom.

:When the shuttle G, is thrown into the shuttle-box at the left-hand end of the lay (as shown .in Fig. 1) it encounters the picker B, which in turn encounters the check D, and is thereby cushioned. The outward upper end is moved inwardly, thereby-movmg inwardly the check this adjustable connection w, fixed to thelay and E, sothat it crosses the picker slot m, at the right-hand end of the lay ready to cushion the corresponding picker when it is driven outwardly by'the shuttle thrown in the opposite direction. At each flight of the shuttle one picker check acts as a picker cushion and the other is put into cushioning position.

Each picker check is adjust-ably clam ed at its rear end'to the rear 'of the layan as is the same for both checks it will sufiice of the check D.- As shown in Fig. '3, the check has a longitudinal tends a clamping bolt t, carried by a bracket the rear end of the the end a, of'

to describe that slot .9, through which ezicheck is clamped in its adjusted position by means of a clamping nut w, and washer 3 ,a weftgcarrler discharge slot at one end and an apcr'tured front plate at its other end; a picker check at each end of the lay fastene d at its rear end at the back of. the lay, extending across the-outer end of the lay in the path of the neighboring picker, and thence to the front of the lay; two vertically d sposed'levers centrally pivoted at the front of the lay and connected respectively to said picker checks, and a thrust rod connecting said levers at their lower ends, said thrust rod neathboth shuttle-boxes and extending forward of the lay opposite the weft-carrier discharge slot therein.

2. An automa'tic'feeler weft-replenishing loom having, in combination, a lay having a Weft-carrier discharge slot at one end and an apertured front plate at its'other end; a picker check at eachend of the lay fastened at one end to the lay, and extendi across the outer end of the lay in-the path of the neighboring at one end to one of said picker checks, and 'a thrust rod connecting said-."levers at their other ends.
